Re: gps navigation

knots, if you've gotten rusty at it, I would say the one thing you need to be aware of is the choice of datums and co-ordinates. In theory all GPS charts in the US will be WGS84 datum and every GPS and program will be preset to match that. In practice? Especially with your older GPS that may have been switched, so never assume the chart and the GPS datum match.

Also, your GPS may be set up to display in DD.MM.SS format, or DD.MM.mm format, and sometimes you can't tell which. Make sure it is reading degrees-minutes-seconds, or all decimal degrees (there ISO engineering standard is simply degrees to five decimal places) or whatever everything can agree on.

As to how to use software or calculate distances and all that good stuff...well at least there, it is usually obvious if something is wrong. But the datum mismatch or format can really slip past you.

There are, or at least recently were, still parts of the US using the NAD27 datum, and if your chart is on that, your GPS can be off by 1/3 of a mile versus reality. Never assume the chart is right, just because the box makes it look precise.

btw is there any way of blocking the sailnet chat feature? believe it or not i'm really not the chatty type and i'm tired of forever accidently going there,plz tell me how and just forget I even asked about navigation!

From what I understand you cannot block the damn thing permanently but if you turn it off when it first appears it will stay turned off for some considerable time. Not sure why but eventually it will pop back up again. Only takes two clicks to kill the thing. "Chat With" and "Turn Off".

I doubt the crowd around my dock has ever even been more than a mile or two away from my marina,a trip down to the next lake would be a major event in fact some rarely leave their slip I seriously doubt any could give me any pointers concerning navigation,somehow I've always managed to muddle myself to where I want to go

Well, then, best you be muddling to clearer waters.

Hah, it's OK mate, I don't take offence, don't worry about it. I'd still love to know where you ended up, accidental p0rn is always the best sort.

Click on the list showing people here, click on the gear icon, click turn off. Usually stays off for a while until a cookie gets reset or the site has some work done.
Don't search for anything though, you never know where you are going to end up.

thanks,i can navigate with what I have,after today I think i'll stick with that lol

Yo knots, good time for you to have a face to face with some of your dock mates. Somebody can show you the ropes. Not real difficult once you get the hang of it. It will beat the heck out of a social networking experience.
